Consumer culture in Japan is where you'll see the collision of Asian and American tastes. More than in the U.S., Japan is where East mashes West. You can get shrimp Filet-o-Fish sandwiches at McDonald's, or pizza with seaweed or squid, and spaghetti with salty plum sauce.
So I supposes I shouldn't be dismayed at the new Coca-Cola flavor, Green Tea Coke. After all, here in the states there seems to be a growiing market for almost anything with green tea added, from soap and shampoos to Lipton Ice Tea and Starbucks' Matcha Latte.
But Coke with green tea?
I'm not much of a Coke fan (Pepsi's the choice if I have a cola at all), so I don't care that much about the purity of the soft drink. But it seems heresy to put green tea into the syrupy sweetness. Can you even taste the subtle bitterness?
This fits right in with conversations I've had recently with (non-Asian) co-workers about Lipton's green tea flavored ice tea. I pointed out that Asians don't sweeten their tea.
